One of four 4-foot fans in the rooftop air-filtration system of the San Francisco Chronicle newspaper printing plant. Closed and abandoned in 2009, now wide open to explorers and scrappers. About midnight, mid-week. The air scrubbing system on the roof was a maze of room-sized chambers, fans and filters, with ship-like hatches between them. Good job opening those louvers Riki, I didn’t realize they did that. 156-second exposure in total darkness. Red, white and lime-set Protomachines flashlight, mostly from the adjoining rooms. Fisheye lens.
